The company, which has produced games such as Angry Birds POP!, Mystery Match, Booty Quest, and Castle Creeps TD, has posted revenue growth of 1,904% over the past four years placing it 11th in the overall UK table.

Glasgow-based IT and communications firm, Exsel Group, was the other Scottish company included in the 20th year of the awards, coming in at 27th position with four-year growth of 959%.

Outplay Entertainment was co-founded in 2010 by brothers Richard and Douglas Hare. The company’s games have been downloaded more than 100 million times, with millions of users playing every month.

Douglas Hare had the idea for this third venture, Outplay, in 2008. At the time, he was head of strategic projects at Foundation 9 Entertainment (F9E), a traditional games maker headquartered in Orange County, California.

“We developed and published a relatively simple mobile game as a launch title for the Apple App Store in July of 2008, and I saw an amazing opportunity,” he says. “The market was small and undeveloped then but I knew it would be big.”

But there was a problem. F9E’s customers were all traditional publishers, who used the company’s various studios to develop big-ticket games like Star Wars, The Da Vinci Code, and Harry Potter. These were aimed at consoles and PCs – not smartphones.

“They weren’t interested in moving into mobile,” says Hare. “But I was convinced that was where the action was going to be.”

Undeterred by the challenge – and despite the global recession – Hare left to create Outplay, a novel social and mobile gaming company. ”Very few companies were using the free to play business model back then and the idea of games as a service was only just emerging.”

Hare, 50, and his co-founder and brother Richard tried to launch their new venture in California but quickly ran into problems outsourcing the work. “It became more and more obvious that we’d need to staff-up and do the work internally again.

That realisation got us thinking about different locations and after speaking with Scottish Development International and Scottish Enterprise we made the decision to move back to Scotland. Hare says: “California was a lovely but very expensive place to live and start a new company. Scotland had a long history in gaming, particularly Dundee, where we ultimately opened the studio.”

The move was the making of the business. British venture capitalists were eager to back these proven entrepreneurs, and it took just four months to close their first round of funding. “It took us over five years to reach profitability which is not uncommon for VC-backed businesses but which was psychologically challenging for Richard and me.”

But 2015 and 2016 saw revenues more than double year-on-year and 2017 is going to be another big growth year, Hare says. “We started small and built on our success, and now we are very bullish about the future.”
